This invention relates to carlines more particularly designed for use infreighticar roof frames, and has for an object the provision of a simplyconstructed, though strongly braced carline that is reinforced at thepoints of attachment to the side frame members or side plates, with theresult of making the carline, as a whole, Stronger for the resistance ofall vertical, horizontal and torsional strains, and of preventinga hingeact-ion at the points where the carline is secured to the side framemembers or plates.

The invention has for further objects a general stifening andyreinforcing of the root trame, and such other improvementsl oradvantages in construction and operation as are found to obtain in thestructures and de-` vices hereinafter described or claimed.

In the accompanying drawings, forming a part of this specification, andshowing, for purposes of exemplilication a preferred form and manner inwhich the inventionA may be en embodied and practiced, but withoutlimiting the claimed invention specifically to such illustrativeinstance or instances:

a portion of a car roof frame provided with a carline embodying theinvention, and showing said frame and the sheathing in section and thecarline partly in section and partly in elevation;

Fig. 2 is a plan view of the same;

Fig. 3 is a perspective view of an end portion of the carline;

Fig. 4 is a vertical transverse section of the carline taken on the line4-4 of Fig. 2, and

Fig. 5 is another vertical transverse section of the carline taken onthe line 5-5 of Fig. 2.

The same characters of reference indicate the same parts throughout theVseveral views.

Referring to the drawings, there is indicated at 11 the side plates ofthe roof frame, suitably secured as shown at 12 to side poles 18, therebeing a plurality of such poles disposed at intervals alongeach side ofthe car.

Mounted on the upper end of the rows of side poles 13 are longitudinallyextending Z-bars 14, the vertical webs 15 of which are suitably securedas shown at 16to the side plates 11. The top horizontal flanges 17 ofthe aforesaid Z-bars 14 respectively extend laterally inwardly from theinside :faces of Figure 1 is a vertical transverse section of.

cent the apex 23 of the carline to,V the endsl 24, as shown in Fig. 1.The horizontal side flanges 25 of the carline may taper inwe-.rdlj;7toward the longitudinal center of the carline, as shown at 26. `Towardthe side plates 11 ofk the car roof frame, the side carline flanges 25,which extend oppositely from the central reinforcing rib 2,2), are bentupwardly as shown at 27 to form vertical stiffening ,flanges 28 situatedat the oppositek ds ofy the carlinfe, and these stifening flanges 28'maytaper downwardly from the opposite ends of the carl'ine teward itslongitudinal center and into the side flanges 25, as indicated at 29 inFig'. l. The centrai rib 22, which is relatively lower at the ends y ofthe carline than at its apex, is thus reinforced at the opposite carlineends yby means of vertical flanges that exten-d parallel with saidcentral rib along its opposite sides. y

Further kreinforcing of the opposite ends of the carline is effected bybending the horizontal flanges 25 and the central rib 22 downwardly, asshown at 30, so that these flanges 25 and rib 22 overlap, as shown at 32the vertical web 15 of the Z-bar 14.V The opposite ends of the carlineare suitably secured to the trame by bolts or rivets'l passed throughthejcarline flanges 25 and the top horizontal flanges 17 of the Z-bars14.r By bending the opposite ends of the and stresses are brought tobear on the side members and carline ends at the pointsy of attachment,especially when the car is tilted while turning curves, such stressestending to effect a relative movement of the carlines and side membersand to rip the fastenings apart or bend the parts out of their truerelative positions.

The invention as hereinabove set forth is embodied in a particular formof construction but may be variously embodied within the scope of theclaims hereinafter made.

claim:

l. In a car roof, in combination: a roof frame including side Z-barssecured to the side members of said frame and having their tophorizontal flanges extended inwardly beyond-the inner faces of said sidemembers; a carline extended between said Z-ba-rs and constituted of asingle steel bar formed with a central upstanding reinforcing rib thatextends from end to end of the carline and tapers downwardly from theapex thereof to itsropposite end, and with side horizontal flangesextending along the opposite sides of said reinforcing rib, theaforesaid rib and side flanges being bent downwardly at vthe oppositeends of the carline over against the outer faces of the vertical webs ofthe aforesaidv Z-bars; and means for securing the horizontal fianges ofsaid carline to the top horizontal flanges of Vsaid Z-bars,substantially as specified.

Q. A carline comprising a rigidifying rib of constant width having sidesdecreasing in depth from the ridge portion toward each end7 said sidesterminating in lateral flanges increasing in width as the sides decreasein depth, said lateral ianges being bent transversely from a point backof the eaves towards the eaves.

3. A carline comprising a central rigidifying rib of constant width fromend to end and having sides decreasing in depth toward the eaves from apoint at each side of the ridge, said carline being of constant widthfrom a point short of the eaves toward the eaves, said sides havinglateral fianges, a portion of the flanges increasing in width toward thecaves and a portion of the material of said lateral flanges being struckupwardly from said point short of the eaves out to the eaves end-s ofsaid carline.

il. A carline comprising a rigidifying rib 0f constant width havingsides terminating in laterall flanges in a common plane, said sidesdecreasing in height from the ridge toward the eaves and said lateralflanges increasing in width toward the eaves, a portion of said lateralflanges at each eaves end being flanged upwardly.

5. A carline comprising a rigidifying rib having sides decreasing indepth toward the eaves from a point adjacent the ridge, said .sideshaving flanges, portions of the flanges being bent upwardly, saidportions decreasing in depth toward the ridge from a point adjacent theeaves end of the carline. `THOMAS NATHAN RUSSELL.
